I'm guessing things here without checking, but some issues may be: * pretty sure JNA mlockall() to lock the cassandra memory from swapping is not available https://issues.apache.org/jira/browse/CASSANDRA-1214
* Creating hard links for the snapshots will be different, not sure exactly how different https://github.com/apache/cassandra/blob/cassandra-0.8.6/src/java/org/apache/cassandra/utils/CLibrary.java#L160 * features that try to avoid polluting the os disk cache will not work * off heap row cache ?? * You will have a greater chance of finding help on *nix than windows. Hope that helps. ----------------- Aaron Morton Freelance Cassandra Developer @aaronmorton http://www.thelastpickle.com On 4/10/2011, at 10:31 AM, Bryce Godfrey wrote: > I’m wondering what the consensus is for running a Cassandra cluster on top of > Windows boxes?
